Advanced, high power and energy battery electrode manufactured by co-extrusion printing

Abstract

A battery has an anode, a separator adjacent the anode, and a cathode adjacent the separator opposite the anode, the cathode comprising interdigitated stripes of materials, one of the materials forming a pore channel.

What is claimed is: 
     
       1. A battery, comprising:
 an anode; 
 a separator adjacent the anode; and 
 a cathode adjacent the separator opposite the anode, the cathode comprising interdigitated stripes of first and second materials, the first material having a lower lithium concentration than the second material, one of the materials forming a pore channel. 
 
     
     
       2. The battery of  claim 1 , further comprising current collectors adjacent to the anode and the cathode opposite the separator. 
     
     
       3. The battery of  claim 1 , wherein the pore channel is formed of the first material. 
     
     
       4. The battery of  claim 1 , wherein the cathode comprises an active material of either lithium cobalt oxide or lithium nickel cobalt manganese oxide. 
     
     
       5. The battery of  claim 1 , wherein the cathode comprises an active material of one of: lithium nickel cobalt aluminum oxide (NCA), lithium manganese oxide (LMO), or lithium iron phosphate (LFeP). 
     
     
       6. The battery of  claim 1 , wherein the anode comprises interdigitated stripes of materials, one of the materials forming a pore channel.
